“…In general, scientific studies on OP pesticides are scarcer than those on OCs. Among those with OPs, the most important are in river sediments (Masiá et al, 2015;Montuori et al, 2016;Hunt et al, 2016;Ccanccapa et al, 2016) and coastal area sediments (Smalling et al, 2013;Selvaraj et al, 2014;Montuori et al, 2015;Pintado-Herrera et al, 2017).…”

ABSTRACT:The knowledge of pesticide residual concentrations in the environment is important to understand the threats to the environment and human health, especially when natural resources are used for human consumption. In this context, this study aimed to assess the potential ecological risk and respective sources of sediment contamination by organochlorine and organophosphorus pesticides. The study site was an urban lake located in Cascavel city, western Paraná state, Brazil, where the history of land use and occupation in the urban environment is typically agricultural. Surface sediment samples were collected every three months from April 2010 to June 2013 at five different collection points, totaling 65 samples. Analyses showed that contamination by organochlorine pesticides is related to agricultural activities in the past, with a low ecological risk to benthic organisms. Conversely, organophosphorus pesticides presented a recent and continuous contamination from urban activities, with a risk coefficient, especially for disulfoton, indicating a significant potential adverse effect on organisms. However, in general, the obtained results did not indicate an immediate risk to public health.

“…The p ', p'-DDT, even below the TEL, was quantified in at least one sample at each of the sampling points, totaling 12 quantified samples, but at concentrations lower than ERL, in which adverse damages are rarely observed. Table 8 shows the ecological risk for OFs compounds, and has already been developed in the studies carried out by the Cristale et al (2013); Chen et al (2014); Selvaraj et al (2014); Ccanccapa et al (2016); Montuori et al (2016). (Klosterhaus et al, 2003); considering: RQ < 1.0 (there is no significant risk on biota); 1.0 ≤ RQ <10 (small potential for adverse effects on biota); 10 ≤ RQ <100 (significant potential for adverse effects on biota); RQ ≥ 100 (potential adverse effects on biota to be expected).…”

“…The Indian context is still different in the sense that there is no concrete stance on the use of BPA in foodcontact plastics. Some research studies are available in India stating the high incidence of endocrine disorders 2 , increased rate of thyroid-related disorders 68 ; presence of BPA in food and environmental samples 7,[69][70][71][72][73][74][75][76] . These studies provide substantial evidence of the presence of BPA in articles, leaching into food substances and causing endocrine disruption in humans.…”

Keywords: BPA policy, endocrine disruptor, low-dose effects, toxicity, tolerable daily intake.ENDOCRINE disorders like infertility, obesity, thyroid disorders, male and female reproductive abnormalities have been increasing in the recent past. These disorders have been identified as significant public health burdens affecting more than 5% of the US population. Disorders like diabetes mellitus, obesity, metabolic disorders, osteoporosis, osteopenia, erectile dysfunction in male and thyroiditis are found to be more prevalent among the US population 1 . A five-fold increase of endocrine disorders like infertility, polycystic ovary syndrome (PCOS), thyroid, amenorrhea, hyperprolactinemia, menopause and hormonal contraception in Indian women was reported 2 . Besides other causes, exposure to synthetic chemicals like agrochemicals, industrial chemicals including solvents, plastics and plasticizers is one of the reasons for such endocrine disruptions 3 . These chemical compounds potentially disrupt hormonal functions and are collectively called as endocrine disrupting compounds (EDCs). These chemicals enter human body through oral ingestion, respiratory and/or dermal exposure. Through different mechanisms, EDCs bind to the hormonal receptors and affect the usual hormone actions. Bisphenol A (BPA) is one such synthetic chemical used largely in the manufacturing of polycarbonate (PC) plastics and epoxy resins. These PC plastics are widely used in various home appliances, such as kitchen wares, storage containers, etc.; thus exposure to humans is apparently high. BPA is leached into food substances under various circumstances via elevated temperature, longer storage or shelf-life, acidic pH, high pressure, etc. [3][4][5][6][7] . The repeated use of containers is also attributed to the high migration of this compound 8 . The potential endocrine-disrupting effects of this compound have been studied widely. Though many scientific evidences have been produced, the results vary on the level of toxicity of BPA on animal and human model systems. The governments, international monitoring agencies and various national level federal agencies are not certain about whether or not to restrict the use of this compound in food-contact materials. The dose responses showed that discrepancies lie across species level as the human testis model is more sensitive than that of rat and other animal model studies 9 . These discrepancies lead to a critical status quo where most experiments are conducted in rat and other animal models. To restrict the use of BPA in food-contact materials, we need conclusive evidence suggesting significant toxicity over hormone systems. This article intends to examine the position of developing countries especially India at present on the regulation of BPA.
