A Review of Microbial Biosorbents

GwynneL.

A New Strategy for Heavy Metal Polluted Environments: A Review of Microbial Biosorbents SUMMARY: Heavy metal pollution is a serious environmental problem and the chemical/physical means of getting rid of them are either too expensive, not effective for low quantities of pollutants, or produce a lot of toxic waste. One solution is to use microbes… Continue reading A Review of Microbial Biosorbents

Impacts of Biogeochemical Redox Processes

GwynneL.

Biogeochemical Redox Processes and their Impact on Contaminant Dynamics SUMMARY: Reduction and oxidation reactions are the drivers behind many biological processes. Energy is both stored and transferred through these reactions. This article talks about the various redox reactions that can occur, both biotically and abiotically, and how that affects both biogeochemical cycles and contaminants. The… Continue reading Impacts of Biogeochemical Redox Processes

Frequency of Microplastics in Mesopelagic Fishes from the Northwest Atlantic

GwynneL.

Frequency of Microplastics in Mesopelagic Fishes from the Northwest Atlantic SUMMARY: In this experiment, the researchers sampled dead mesopelagic fish from the Northwest Atlantic Mid-Ocean area (between Ireland and Newfoundland). The water and the fish guts were strained for microplastics. Researchers found that 73% of the fish had microplastics in their stomach. Most of the… Continue reading Frequency of Microplastics in Mesopelagic Fishes from the Northwest Atlantic

Protozoa in Wastewater Treatment Processes

GwynneL.

Protozoa in wastewater treatment processes: A minireview SUMMARY: This is a short review of the role protozoa play in wastewater treatment plants. Most of the protozoa are ciliates and they graze on bacteria, excrete nitrogen, phosphorus, and carbon waste, and are used as indicators of water quality. Toxins such as heavy metals, salts, and other… Continue reading Protozoa in Wastewater Treatment Processes

Investigating Microplastics on Land

GwynneL.

Microplastics as an emerging threat to terrestrial ecosystems (NOT OPEN ACCESS) SUMMARY: Though there has been a lot of research on microplastics in aquatic environments, there aren’t studies looking into the effects of microplastics on land. Researchers in this article suspect that there may be more microplastics on land than in the oceans; organisms that… Continue reading Investigating Microplastics on Land
