Although the effects of nitrogen (N) fertilization on soil microflora have been well studied, the effects should be verified across soil types and N-added levels. To understand the impacts of N fertilization on shifts in soil biological traits and bacterial communities and to further explore the coupling mediation of these parameters with respect to crop yields, we sampled soils from three experimental sites (each site received three levels of N fertilization (0, 168 and 312 kg N ha−1)) that share the same climatic conditions but have different soil types (clay, alluvial and sandy soils).

The Mediterranean Sea is affected by one of the most significant plastic pollution worldwide. This review critically evaluates the most recent literature on the presence of microplastics in sediments, suggested to be long term sinks and have a high potential to accumulate this kind of marine debris. A picture of microplastic levels in coastal environments is given, evidencing information gaps and considering also estuary, lagoons and areas influenced by the contribution of rivers. A wide range of contamination levels has been found, with the highest in lagoon and estuary environments.

Environmental concerns arising from the over-dredging of sand have led to restrictions on its extraction across India, with direct economic impacts on concrete construction. A suitable environmentally friendly alternative to sand must be found to match the huge demand from the concrete construction industry. At the same time, waste plastic is rarely recycled in India, with as much as 40% left in landfill. The dumping of such materials which degrade at extremely low rates meaning they persist in the environment is a long-term environmental concern.
