Occupancy of waste micro plastic particles in the beach sand is found hazardous sea livings as well as creates the environmental issues. Many research attempts have been made to short out them. This i...
Microplastics (MPs) and nanoplastics (NPs) have caused global environmental concerns due to their ubiquitous existence in our surrounding environment and the potential threats posed to the ecosystem a...
The production and consumption of plastic products had been steadily increasing over the years, leading to more plastic waste entering the environment. Plastic pollution is ubiquitous and comes in man...
Plastic is widely used in every sector due to its stability, durability, and low cost. The widespread use of plastic results in the compilation of plastic waste in the environment. The buildup of such...
Plastic pollution is now present in all areas of our planet, including its last wilderness, Antarctica, and the plastic crisis has further escalated because of COVID-19. The pandemic has caused a sign...
Plastic pollution in the natural environment is causing increasing concern at both the local and global scale. Understanding the dispersion of plastic through the environment is of key importance for ...
Plastic pollution exacerbated by the excessive use of synthetic plastics and its recalcitrance has been recognized among the most pressing global threats. Microbial degradation of plastics has gained ...
Plastics show the strongest production growth of all bulk materials and are already responsible for 4.5% of global greenhouse gas emissions...
Plastic additives are a diverse group of chemical compounds added to plastic products to give them their unique physical-chemical properties. Persistent, mobile, and toxic (PMT) plastic additives are ...
Agricultural plastic mulches offer great benefits such as higher yields and lower pesticide use. Yet, plastic mulches may disintegrate over time and fragment into smaller debris. Such plastic debris i...
To investigate this, we collected soil samples at 0-10 cm and 10-40 cm depth from three fields covered with black mulch film for three consecutive years. Three fields without any reported plastic use ...
With 89-206 fragments ha...
Although the identified plastic levels are lower than those reported in comparable studies, our results still suggest that plastic mulching functions as a source of plastic debris in agricultural syst...
