Microbes from humics lakes surprise - bacteria and algae produced omega-3 fatty acids from microplastics. The environmental fate of microplastics has been difficult to trace. A research group used carbon isotope labeling to follow the fate of polyethylene in the food chain. To the researchers surprise, plastic carbon was transformed into beneficial fatty acids, omega-3 and omega-6, by the microbes originating from humic lakes. Source 3c.
Facts on the ground: How microplastics in the soil contribute to environmental pollution. Plastic is a major threat to the environment. Of particular ecological risk is its manifestation as microplastics (<5 mm in size) in the agricultural environment. Scientists addressed this issue in a recent study, looking into the levels, shapes, and sizes of microplastics in Korean agricultural soils. They reported new insights on the agricultural sources of microplastics, contributing to a better understanding on their role in environmental pollution. Source 7r.
