Microplastics in the environment produced by decomposition of globally increasing waste plastics have become a dominant component of both water and air pollution. To examine the potential toxicological effects of microplastics on human cells, the cultured human alveolar A549 cells were exposed to polystyrene microplastics (PS-MPs) of 1 and 10 μm diameter as a model of the environmental contaminants. Both sizes caused a significant reduction in cell proliferation but exhibited little cytotoxicity, as measured by the maintenance of cell viabilities determined by trypan blue staining and by Calcein-AM staining. The cell viabilities did not drop below 93% even at concentrations of PS-MPs as high as 100 μg/mL. Despite these high viabilities, further assays revealed a population level decrease in metabolic activity parallel in time with a dramatic decrease in proliferation rate in PS-MP exposed cells. Furthermore, phase contrast imaging of live cells at 72 h revealed major changes in the morphology of cells exposed to microplastics, as well as the uptake of multiple 1 μm PS-MPs into the cells. Confocal fluorescent microscopy at 24 h of exposure confirmed the incorporation of 1 μm PS-MPs. These disturbances at the proliferative and cytoskeletal levels of human cells lead us to propose that airborne polystyrene microplastics may have toxicologic consequences. This is the first report of exposure of human cells to an environmental contaminant resulting in the dual effects of inhibition of cell proliferation and major changes in cell morphology. Our results make clear that human exposure to microplastic pollution has significant consequence and potential for harm to humans.
1 Moreover, brethren, I declare unto you the gospel which I preached unto you, which also ye have received, and wherein ye stand;
2 by which also ye are saved, if ye keep in memory what I preached unto you, unless ye have believed in vain.
3 For I delivered unto you first of all that which I also received, how that Christ died for our sins according to the scriptures;
4 and that he was buried, and that he rose again the third day according to the scriptures:
1 Now concerning spiritual gifts, brethren, I would not have you ignorant.
2 Ye know that ye were Gentiles, carried away unto these dumb idols, even as ye were led.
3 Wherefore I give you to understand, that no man speaking by the Spirit of God calleth Jesus accursed: and that no man can say that Jesus is the Lord, but by the Holy Ghost.
4 Now there are diversities of gifts, but the same Spirit.
5 And there are differences of administrations, but the same Lord.
6 And there are diversities of operations, but it is the same God which worketh all in all.
7 But the manifestation of the Spirit is given to every man to profit withal.
8 For to one is given by the Spirit the word of wisdom; to another the word of knowledge by the same Spirit;
9 to another faith by the same Spirit; to another the gifts of healing by the same Spirit;
10 to another the working of miracles; to another prophecy; to another discerning of spirits; to another divers kinds of tongues; to another the interpretation of tongues:
11 but all these worketh that one and the selfsame Spirit, dividing to every man severally as he will.
12 For as the body is one, and hath many members, and all the members of that one body, being many, are one body: so also is Christ.
13 For by one Spirit are we all baptized into one body, whether we be Jews or Gentiles, whether we be bond or free; and have been all made to drink into one Spirit.
1 Therefore leaving the principles of the doctrine of Christ, let us go on unto perfection; not laying again the foundation of repentance from dead works, and of faith toward God,
2 of the doctrine of baptisms, and of laying on of hands, and of resurrection of the dead, and of eternal judgment.
3 And this will we do, if God permit.
4 For it is impossible for those who were once enlightened, and have tasted of the heavenly gift, and were made partakers of the Holy Ghost,
5 and have tasted the good word of God, and the powers of the world to come,
6 if they shall fall away, to renew them again unto repentance; seeing they crucify to themselves the Son of God afresh, and put him to an open shame.
7 For the earth which drinketh in the rain that cometh oft upon it, and bringeth forth herbs meet for them by whom it is dressed, receiveth blessing from God:
8 but that which beareth thorns and briers is rejected, and is nigh unto cursing; whose end is to be burned.
1 Who hath believed our report? and to whom is the arm of the Lord revealed?
2 For he shall grow up before him as a tender plant,and as a root out of a dry ground:he hath no form nor comeliness;and when we shall see him,there is no beauty that we should desire him.
3 He is despised and rejected of men;a man of sorrows, and acquainted with grief:and we hid as it were our faces from him;he was despised, and we esteemed him not.
4 Surely he hath borne our griefs,and carried our sorrows:yet we did esteem him stricken,smitten of God, and afflicted.
5 But he was wounded for our transgressions,he was bruised for our iniquities:the chastisement of our peace was upon him;and with his stripes we are healed.
6 All we like sheep have gone astray;we have turned every one to his own way;and the Lord hath laid on him the iniquity of us all.
7 He was oppressed, and he was afflicted,yet he opened not his mouth:he is brought as a lamb to the slaughter,and as a sheep before her shearers is dumb,so he openeth not his mouth.
8 He was taken from prison and from judgment:and who shall declare his generation? for he was cut off out of the land of the living:for the transgression of my people was he stricken.
9 And he made his grave with the wicked,and with the rich in his death;because he had done no violence,neither was any deceit in his mouth.
10 Yet it pleased the Lord to bruise him;he hath put him to grief:when thou shalt make his soul an offering for sin,he shall see his seed, he shall prolong his days,and the pleasure of the Lord shall prosper in his hand.
11 He shall see of the travail of his soul, and shall be satisfied:by his knowledge shall my righteous servant justify many;for he shall bear their iniquities.
12 Therefore will I divide him a portion with the great,and he shall divide the spoil with the strong;because he hath poured out his soul unto death:and he was numbered with the transgressors;and he bare the sin of many,and made intercession for the transgressors.

Abstract
Mercury (Hg) is a persistent bio-accumulative toxic metal with unique physicochemical properties of public health concern since their natural and anthropogenic diffusions still induce high risk to human and environmental health. The goal of this review was to analyze scientific literature evaluating the role of global concerns over Hg exposure due to human exposure to ingestion of contaminated seafood (methyl-Hg) as well as elemental Hg levels of dental amalgam fillings (metallic Hg), vaccines (ethyl-Hg) and contaminated water and air (Hg chloride). Mercury has been recognized as a neurotoxicant as well as immunotoxic and designated by the World Health Organization as one of the ten most dangerous chemicals to public health. It has been shown that the half-life of inorganic Hg in human brains is several years to several decades. Mercury occurs in the environment under different chemical forms as elemental Hg (metallic), inorganic and organic Hg. Despite the raising understanding of the Hg toxicokinetics, there is still fully justified to further explore the emerging theories about its bioavailability and adverse effects in humans. In this review, we describe current research and emerging trends in Hg toxicity with the purpose of providing up-to-date information for a better understanding of the kinetics of this metal, presenting comprehensive knowledge on published data analyzing its metabolism, interaction with other metals, distribution, internal doses and targets, and reservoir organs.

Conclusions
Like all types of research, systematic reviews and meta-analyses have both potential strengths and weaknesses. With the growth of renal clinical studies, an increasing number of these types of summary publications will certainly become available to nephrologists, researchers, administrators, and policy makers who seek to keep abreast of recent developments. To maximize their advantages, it is essential that future reviews be conducted and reported properly, with judicious interpretation by the discriminating reader.

Abstract
Background & aims
The relationship between mercury and autism spectrum disorders (ASD) has always been a topic of controversy among researchers. This study aimed to assess the relationship between ASD and mercury levels in hair, urine, blood, red blood cells (RBC), and brain through a meta-analysis.
Methods
A systematic search was performed in several databases including PubMed, ISI Web of Science, Cochrane register of controlled trials, Google Scholar, Scopus, and MagIran until June 2017. Case-control studies evaluating concentration of total mercury in different tissues of ASD patients and comparing them to the healthy subjects (control group) were identified. Necessary data were extracted and random effects model was used to calculate overall effect and its 95% corresponding confidence interval (CI) from the effect sizes.
Results
A total of 44 studies were identified that met the necessary criteria for meta-analysis. The mercury level in whole blood (Hedges = 0.43, 95% CI: 0.12, 0.74, P = 0.007), RBC (Hedges = 1.61, 95% CI: 0.83, 2.38, P < 0.001), and brain (0.61 ng/g, 95% CI, 0.02, 1.19, P = 0.043) was significantly higher in ASD patients than healthy subjects, whereas mercury level in hair (−0.14 mg/g, 95% CI: −0.28, −0.01, P = 0.039) was significantly lower in ASD patients than healthy subjects. The mercury level in urine was not significantly different between ASD patients and healthy subjects (0.51 mg/g creatinine, 95% CI: −0.14, 1.16, P = 0.121).
Conclusions
Results of the current meta-analysis revealed that mercury is an important causal factor in the etiology of ASD. It seems that the detoxification and excretory mechanisms are impaired in ASD patients which lead to accumulation of mercury in the body. Future additional studies on mercury levels in different tissues of ASD patients should be undertaken.
