Industrial Pollution Evaluation through Enzymatic Biomarkers at Different Localities of El-Sadat Industrial City, Menofia, Egypt.

Abstract

Industrial pollution is one of the most dangerous that is a continuous threat for humanity. Evaluation of that pollution is the main aim of the current study through the detection of the accumulated heavy metals in its surrounding habitats mainly soil and flora as well as the response of insects towards this pollution. Therefore, seasonal collection of three different insect species were performed in addition to soil and the common plant; Zilla spina, at different sites of El-Sadat industrial city, Menofia, Egypt for four successive seasons during 2016 to 2017. The Acetylcholinesterase (AChE) and lactate dehydrogenase (LDH) extracted from the homogenate of the chosen insects were used as biomarkers for heavy metals pollution. Also, heavy metal contents in plant and soil samples were analyzed. Results showed varied activities for the investigated biomarkers depending on the study sites, providing a representative picture to the environmental state of that areas.

Pollution Indices, Floral Coverage and Newly Enzymatic Biomarker for Soil Heavy Metal Contamination Due to Industrial Activities At 6th October City, Egypt

“…Zilla spinosa (Family: Brassicaceae), Tamarix nilotica (Family: Tamaricaceae) and Conyza dioscoridis (Family: Compositae) are the most recorded species in study sites. In special, Zilla spinosa was the dominant species in all vegetation cover at different study sites, which agrees with Bream et al (2019). Due to their large biomass, rapid growth, and capacity to adapt to extreme climates in nature, native vegetation on mining sites should be used as much as possible as a better indicator of reclamation effectiveness (Bandyopadhyay, 2022).…”

“…This impact is more related to increased heavy metal emissions in heavy and medium areas than others. Bream et al (2019) stated the increase in metals is correlated with industrial pollution sources. Anthropogenic activities are the primary source of soil arsenic (Bohn et al, 1979).…”

“…Different xenobiotics and heavy metals were reacted to by changes in detoxification enzyme activity via metabolism, degradation, or even antioxidative activity to preserve vital body organs or molecules (Wilczek et al, 2008). As a result, the activity of detoxifying enzymes has been widely employed in monitoring environmental pollution as an early sensitive, responsive instrument and efficient biochemical biomarker (Praet et al, 2014;Bream et al, 2019). The maximum levels of all metals, As, Pb, Ni, and Hg, were found in the soil at Industrial 1 and 4 compared to the control site in this study.…”

Morphometric Comparison Between Different Populations of Darkling Beetles “Pimilia nilotica (Coleoptera: Tenebrionidae)” In Egypt

“…Although insects include almost 60% of the described eukaryotic animals worldwide, the morphological measurements and comparison of the effect of isolation and habitat still lack for most insect groups, including the beetles (Coleoptera) (Riad, 2019). Family Tenebrionidae is one of the largest families of the order Coleoptera, which includes more than 20000 known species of nearly 1700 genera of worldwide distribution (Booth et al, 1990 andBream et al, 2019). Despite the fact that among all families of beetles, Tenebrionidae (darkling beetles) positions 7 th as far as species diversity, the absence of information of the phylogeny and systematics of this group and its subfamilies and clans (for example, it's monophyly) has been questioned (Hassan et al, 2017a).…”

Aquatic insects as a biomonitoring and bioindicators for trace metals in the contaminated Al-Mahmoudia Canal, River Nile, Egypt

“…The levels of zinc and copper in sediment samples taken at the current study sites were below the WHO's permitted guideline (2004). Heavy metal leaking into the soil's deeper layers and groundwater could be attributed to the lower Zn content (Bream et al, 2019). Furthermore, iron behaviour could be linked to the lowest amount of Zn in one location during the fall and its absence in another.…”
