The advancement in science and technology has led to the discovery formulations of various cheaper alternatives our day commodities. Plastic is one them. Plasticisers include a group chemicals that increase flexibility plastics so they can be moulded into forms use. plasticisers have number health hazards when leach out environment. This review going comparative discussion, on effects different...

A single species stage-structured model incorporating both toxicant and harvesting is proposed and studied. It is shown that toxicant has no influence on the persistent property of the system. The existence of the bionomic equilibrium is also studied. After that, we consider the system with variable harvest effect; sufficient conditions are obtained for the global stability of bionomic equilibr...

Changes in Cigarettes Over the Past Several Decades 152 Changes in Design, Curing, and Composition 153 Differences Across Brands in Toxicant Yields 154 Changes in Tobacco-Specific Nitrosamine and Benzo[a]pyrene Levels Over Time 155 Differences in Toxicant Yields Across Countries 155 Low-Tar Cigarettes Do Not Reduce Risk of Lung Cancer 157 Overall Death Rates for Lung Cancer Indicate Increased R...

Omics is a term of concept including a large-scale data in biology. Toxicogenomics is paid more attention to many researchers to investigating the genome-scale genes/proteins interaction, expression pattern and function in exposed state to specific toxicant or toxicant-related environment. The ultimate goal of toxicogenomics identifies functional context among the group of genes that are differ...

As man-made chemicals (anthropogenic) are increasing in number and amount of use, it is not uncommon for farmers, ranchers, consultants, or veterinarians to suspect a xenobiotic (strange or foreign substance) as the cause of reproductive failures. In this article, the authors discuss toxicants that have been shown to affect reproduction, with emphasis on food-producing animals and fowl. The dis...

An appropriate approach to assess the effect of toxicants on aquatic animals is to monitor behavioral endpoints, as they are a link between physiological and ecological processes. A group that can be exposed long-term to low toxic concentrations is benthic macroinvertebrates, as their mobility in aquatic ecosystems is relatively limited. Therefore, the study of behavioral long-term effects in t...

Inhalable, noncombustible cannabis products are playing a central role in the expansion of the medical and recreational use of cannabis. In particular, the practice of "dabbing" with butane hash oil has emerged with great popularity in states that have legalized cannabis. Despite their growing popularity, the degradation product profiles of these new products have not been extensively investiga...
