Decline of the Beluga whale population in the upper estuary of the St. Lawrence River may be related to the high content of toxic metals and organic chemicals in their tissues. For three years, the National Water Research Institute has conducted research cruises of the St. Lawrence River to identify the major toxic chemical pollutants in the river and to determine their transport to, and fate in, the upper estuary. The impact of toxic chemicals in the estuarine zone is tied not only to their fate in the increasing salinity and turbidity zone of the upper estuary but to their source, transport mechanisms, and fate in the upstream river.

Current problem facing researchers globally is microplastics as well as toxic chemical pollution of the ecosystem. Microplastics carry toxic chemicals in the ecosystem.serving as a vector for transport. In this study, a review of the literature has been conducted with the following objectives: (1) to summarise the concentrations of toxic chemicals such heavy metals and hydrophobic organic contaminants sorped on microplastics; (2) to evaluate their spatial distribution regarding adsorbed contaminant (3) to discuss plausible mechanism by which microplastics adsorp or desorp toxic chemicals in the environment; (4) to discuss implications of their occurrence in air, water and soil media; and (5) to discuss the impact of ingested microplastics to human health. Microplastics are ubiquitous environmental contaminant. Concentrations of sorped toxic chemical varied with location which represents a local problem; industrialized areas (especially areas experiencing crude oil related activities or have history of crude oil pollution) have higher concentrations than less industrialized areas. Ingestion of microplastics has been demonstrated in a range of marine and soil organisms as well as edible plants, thus possible contaminating the base of the food-web. Potential health effect to human is by particle localization, chemical toxicity and microbal toxins. We conclude by highlighting the gap in knowledge and suggesting key future areas of research for scientists and policymakers.

Good agricultural practices (GAPs) and good handling practices (GHPs) encompass the general procedures that growers, packers and processors of fresh fruits and vegetables should follow to ensure the safety of their product. GAPs usually deal with preharvest practices (i.e., in the field), while GHPs cover postharvest practices, including packing, storage and shipping. This factsheet covers GAPs relating to packing operation sanitation. There are seven other Florida Cooperative Extension factsheets in the ‘Food Safety on the Farm’ series that focus on specific aspects of the GAPs program and how they relate to Florida crops and practices. Under the new Food Safety Modernization Act (FSMA), GAPs are a foundation of the Produce Safety Rule (PSR). Other than for round tomatoes in Florida (T-GAPs regulation), GAPs have mainly been a voluntary program. Additionally the PSR mandates all non-exempt operations to follow these new FSMA federal guidelines (6), but all exempt commodities and for those producers exporting to foreign countries, GAPs may still be required. Both the mandatory PSR and GAPs aim to reduce the foodborne illness burden associated with produce.
