“…After drinking exposure, the organics, heavy metals and other pollutants in the leachate could be absorbed into blood or other body fluid and produce free radicals via autoxidation or by enzyme-catalyzed oxidation [6][7][8][9][10][11]. Under normal condition, generated free radicals could be cleaved by the antioxidant system in the tissue.…”

“…Although the potential damages of these pollutants on mammals have been reported by large amounts of literatures [27,28], it is difficult to assess its toxic mechanisms using single pollutant or several known pollutants due to their synergistic, additive or antagonistic effect [6][7][8][9][10][11][12][13].…”

“…In small mammals, pollutants in landfill leachate were uptaken into the blood and distributed to different tissues and organs after ingestion [6,7]. The brain, heart, kidney, liver and spleen are the five most important organs in mammals, and usually used as models for studying the pathological mechanism due to their involvement in the modulation of assimilation, metabolism, immunity and diseases.…”

“…It is reported that small amounts of landfill leachate could pollute large volume of groundwater, rendering them unusable for domestic and many other purposes [5]. Also, the chemical substances contained in the leachate could be assimilated by any surviving aquatic species, could pass through the food chain, and bioaccumulate over long-term exposure [6,7]. In fact, an increase of adverse health effects, such as low birth weight and increase of birth defects and certain types of cancers, has been reported in people living near landfill sites [8].…”

Heavy metals exert their toxic effects through different mechanisms. Lately, increasing attention has been focused on understanding the long-term ecological effects of chronically exposed populations and communities and their consequences to the ecosystem. The long-term exposure to heavy metals in the environment represents a threat to wild populations, affecting communities and putting ecosystem integrity at risk. Therefore, this type of exposure represents a threat to biodiversity. In the field, metal exposure is generally characterized by low doses and chronic exposures. This type of exposure exerts alterations across levels of biological organization. Distribution and abundance of populations, the community structure and the ecosystem dynamics may be altered. This chapter will focus on how chronically metal exposures in the field affect negatively populations and communities becoming a threat to biodiversity. Also, attention is put on the tools that enable to characterize and analyze the detrimental effects of heavy metal exposure on wild populations. Hence, the use and development of biomarkers in ecotoxicology will be discussed.

The major environmental impact of landfills is emission of pollutants via the leachate and gas pathways. The hepatopancreas of the terrestrial isopod Armadillidium vulgare (Isopoda, Crustacea, Latreille 1804) plays an important role in the bioaccumulation of contaminants, such as heavy metals. To evaluate the effects of landfill leachate treatment, 2 different approaches were applied: 1) the detection of accumulation of trace elements (As, Cd, Cr, Cu, Sb, Zn, Pb, Ni, V) in hepatopancreatic cells, and 2) the evaluation of biological effect of contaminants on fresh hepatopancreatic cells by flow-cytometric analyses. The presence of 2 different cell types (herein referred to as "small" [S] cells and "big" [B] cells, in agreement with the literature based on morphological examinations) was detected for the first time by flow cytometry, which also highlighted their different response to stress stimuli. In particular, B cells appeared more sensitive to landfill leachate treatment, being more damaged in the short term, while S cells seemed more adaptive. Furthermore, S cells could represent a pool from which they are able to differentiate into B cells. These findings were also confirmed by principal component analyses, underlining that S SYBR Green I bright cells correlate with specific chemicals (Ca, Cu, Co), confirming their resistance to stress stimuli, and suggesting that the decrease of specific cell types may prime other elements to replace them in a homeostasis-preservation framework.
