Article
The main objective of this article was to profile the metal accumulation, sources, pollution levels and trends during 6 years in a SW Atlantic coastal system (Bahía Blanca estuary). Subtidal sediment samples were taken from six stations with different human impacts, and chemical element analyses were performed using ICP-OES. As a result, metals ten...
Chapter
The Negro River comprises a multi compartmentalized environment which links Los Andes mountains with the Atlantic Ocean. Due to its relevance in terms of industries, intensive agriculture production and population is considered the second Argentinean river in importance; however, these economic activities have increased the environmental pressure,...

Evidence shows that the majority of aquatic field microplastics (MPs) could be microfibers (MFs) which can be originated directly from massive sources such as textile production and shedding from garments, agricultural textiles and clothes washing. In addition, wear and tear of tyres (TRWPs) emerges as a stealthy major source of micro and nanoplast...

Pesticides have been extensibility used in the control of agricultural and sanitary pests. From World War II onward, more efficient and cheaper synthetic pesticides, such as organochlorine pesticides (OCPs), including DDT, lindane, or endosulfan, replaced the relatively environmentally friendly pesticides. OCPs were widely used worldwide; however,...

Purpose of review: Organochlorine pesticides (OCPs) have been intensely used and produced in South America. Although they were banned before the year 2000 (excepting endosulfan, which has been recently banned in several countries), OCPs remain detectable in marine environments of this continent, sometimes at risky levels for biota. This manuscript...
