TL;DR: The available information on various aspects of sewage sludge application on soil fertility and consequent effects on plant production are reviewed to explore the possibility of exploiting this byproduct for agronomy and horticulture.

TL;DR: Investigation of the influence of pyrolysis temperature on production of wastewater sludge biochar and the properties required for agronomic applications found biochar produced at low temperature was acidic whereas at high temperature it was alkaline in nature.

TL;DR: It was found that most of the heavy metals existed in the oxizable and residual forms after pyrolysis, resulting in a significant reduction in their bioavailability, leading to a very low environmental risk of the biochar.

TL;DR: The distribution and migration of microplastics in soils is summarized, the separation, extraction, and identification methods for monitoring microplastic in soils are highlighted, and the ecological effects and pollution mechanisms of soil micropl Plastic pollution are discussed.

TL;DR: The results indicated a potential pathway of human exposure to slow poisoning by heavy metals due to the indirect utilization of vegetables grown on heavy metal-contaminated soil that was irrigated by contaminated water sources.

TL;DR: This is the first detailed study on the effect of nano- and microplastics on a vascular, terrestrial plant, and the results indicate short-term and transient adverse effects.
