Contaminants such as PCBs and DDT concentrate in the fat of fish. These contaminants can be reduced by up to 50% by preparing and cooking fish properly. Cut off the skin and fat before cooking fish. Then broil, grill, or bake it on a rack so the fat drips off the fish. Don't use the drippings for sauces.

Seed priming technology has been regarded as an efficient method in conveying stress tolerance to various plants species. It is a process of stimulating a specific physiological state in plant system by soaking seeds in water or solution having a wide range of agents (natural/synthetic) prior to sow (Jisha et al. 2013).Findings of Basra et al. suggests that seed …

The present study reports total arsenic and arsenic species in a short rocky intertidal marine food chain in NSW, Australia. Total mean arsenic concentrations increased up the food chain in the ...

The heavy metals transfer from the soil, where they accumulate, to the edible parts of the plants, and then, their entrance in the food chain can represent a source of concern for human health. Among heavy metals, arsenic is one of the most widespread in the soil of Lazio (central region of Italy), where the phytoavailable geogenic arsenic enters the food chain, with …

(2) With respect to arsenic, this Regulation does not apply to mining operations, including concentrating, milling, washing, crushing, grinding, sifting or conveying of a metallic or non-metallic mineral or mineral-bearing substance or rock, unless the operations are carried on, (a) in a plant where smelting, roasting or refining is carried on; or

Extracellular vesicles (EVs) are kinds of two-layer vesicles secreted by cells. They play significant roles in mediating component exchange between cells, signal transduction, and pathological development. Among them, the tumor-derived EVs (TDEVs) are found related to the tumor microenvironment and cancer development.

Bangladesh is one of the countries most vulnerable to climate change, while its people also suffer from a range of environmental hazards linked to the growing prevalence of non-communicable diseases. These diseases are responsible for increasing morbidity and mortality and lead to other stresses within the population. Such stresses create continuous impacts on …

Metals and metalloids are electropositive elements that occur in all ecosystems, although natural concentrations vary according to local geology. Land disturbance in metals-enriched areas can increase erosion and mobilize metals …

fied amount that could leach into the water. Lead, cadmium and arsenic are examples of many possible contaminants that could be present. The pipes, valves, taps and other fittings must be capable of conveying water at a nominated pressure within a prescribed environment, and must be of sufficient strength to contain anticipated internal pressures.

INTRODUCTION. Arsenic is a natural component of the Earth's crust and a constituent of many minerals. Natural geological processes and anthropogenic industrial activities have led to the release and prevalence of this toxic element in many regions and ecosystems (Nordstrom 2002).Depending on the physico-chemical conditions and the biological activities at work, …

Background Low-income and minority communities often face disproportionately high pollutant exposures. The lead crisis in Flint, Michigan, has sparked concern about broader socioeconomic disparities in exposures to drinking water contaminants. Nitrate is commonly found in drinking water, especially in agricultural regions, and epidemiological evidence suggests …

Heavy metals like lead, mercury, and arsenic don't degrade. Instead, they concentrate as they move up the food chain, bioaccumulating in the bodies of fish, wildlife, and people.

The human health significance of other sources of arsenic, such as those via the food chain, need to be further explored, as do the relationships between diet/nutrition and the long-term effects of arsenic, and the dose-response and dose-effect relationships in drinking water.

Arsenic exhibits the most significant toxic effects on the liver, which is one of the major metabolic organs of arsenic, including inflammatory response, fibrosis, and even cancer (Lin et al., 2013). Non-alcoholic fatty liver disease (NAFLD) is a global public health issue, with a prevalence of around 30% in the world population ( Bedogni et al ...

Lower environmental load. Surface Treated Neptune Chain uses no harmful hexavalent chromium in its corrosion resistant surface treatment, nor any other hazardous substances such as lead, cadmium, mercury, or arsenic. Neptune chains are RoHS compliant.

Induction of differentiation is a promising therapeutic strategy against acute myeloid leukemia. However, current differentiation therapies are effective only to specific patient populations. To identify novel differentiation agents with wider efficacy, we developed a phenotypic high-throughput screen with a range of genetically diverse cell lines. From the resulting hits, one …
