Insect life stages are known imperfectly in many cases, and classifications are usually based on adult morphology. This is unfortunate as information on other life stages may be useful for biomonitoring. The major impediment to using elmid (Coleoptera) larvae for freshwater biomonitoring is the lack of larval descriptions and illustrations. Reliable molecular protocols may be used to associate ...

The magnitude and distribution of cypermethrin from total release, over-the-counter foggers was studied in a test room and in residences to facilitate evaluation of regulatory exposure algorithms and new human exposure assessments based upon urine biomonitoring. Surface residue (SR) was evenly distributed in a small test room (3.6 mciro g cypermethrin/cm(2)) where thorough mixing of the aerosol...

Phytoplankton are considered to be one of the most sensitive indicators ecological status lakes. Nowadays, it is essential recognize prospects molecular approach (eDNA metabarcoding) in phytoplankton community assessments and combine them with existing traditional microscopy-based morphological before its standardization. In this study, aim was characterize a natural karstic lake by combining c...

We foresee a new global-scale, ecological approach to biomonitoring emerging within the next decade that can detect ecosystem change accurately, cheaply, and generically. Next-generation sequencing of DNA sampled from the Earth’s environments would provide data for the relative abundance of operational taxonomic units or ecological functions. Machine-learningmethods would then be used to recons...

Experiments on air and biomonitoring were conducted to evaluate pollution impact on the vegetation along the road in Jalgaon City, Maharashtra. The plantation along the roads and mainly includes neem (Aadirachta indica), peepal (Ficus religiosa), banyan (Ficus benghalensis), almond (Terminalia catapa). For biomonitoring, leaf area, total chlorophyll, plant protein were analyzed to study the imp...

This report presents the results of an ozone monitoring experience performed with tobacco indicator plants (Nicotiana tabacum L. cv. 'Bel-W3'). These bioindicators were exposed to ambient air in 23 sites in Northern Italy from 27 April 1987 to 21 October 1987. Typical ozone-induced leaf necrosis was observed in every site. The percentage increase in injured leaf area was estimated weekly and a ...
