background: early puberty is a common worldwide problem. different parameters as genetics, metabolic diseases, obesity, as well as environmental factors may affect the age of puberty. this systematic review aims to survey the related literature on the effects of environmental pollutants and especially organohalogens and phthalates on early puberty. materials and methods: a systematic review of ...

Persistent organic pollutants (POPs) represent a concern for the environment and human health due to their persistence toxicity. Exposure in Slovenia is geographically differentiated because country, as part of former Yugoslavia, has history industry regional contamination – at same time known its clean nature. The PCB pollution Krupa River drew public's attention chemical burden Slovenians, de...

Organic halogens from chlorobleaching of kraft pulp were not as biorecalcitrant as has been assumed. Fifty percent were removed during biotreatment of wastewater, and 50% of the remaining organohalogens faded in fresh water ecosystems in 200 to 400 days. Molecular size seemed not to hinder biodegradation up to sizes of approximately 2000 daltons. Anoxic biodegradation was of prime importance fo...

The paper “Enhanced reactivity of nitrogenous organohalogen formation from plant litter to bacteria," by Wang et al., presents a refreshing take on the natural formation of organohalogens, focusing on halogenation of bacterial cultures and monomers. The hypothesis is novel, the data are clearly presented and discussed, and the results are compelling. After reading the manuscript, I have a few l...
