“…Discharges by papermills have previously been associated with pollution of the environment with PTEs, including Cr, Cd, Cu, Pb and Zn [51, 52]. This pollution can originate from a number of sources, such as metals in the wood entering the papermill, or atmospheric deposition of metals from the smoke stacks [51].…”

The bioaccumulation of Potentially Toxic Elements (PTEs) by benthic invertebrates in estuarine sediments is poorly understood. We sampled and analysed PTEs in sediments and benthic invertebrates from five sites in the Skeena Estuary (British Columbia, Canada), including sites adjacent to an abandoned cannery and a decommissioned papermill. Our aim was to elucidate baseline levels of PTE concentrations at sites that may be recovering from disturbance associated with prior industrial development and identify organisms that could be used to biomonitor the impact of future industrial developments. There was no indication that sediments of the salmon cannery were polluted, but acidic sediments adjacent to the papermill contained elevated concentrations of Cd, Cr, Hg and Pb. Benthic invertebrate community assemblages confirm that sediments have mostly recovered from prior industrial development associated with discharge of papermill sludge. Overall, we did not observe any relationship between PTE concentrations in the sediment and PTE concentrations in invertebrate tissues. However, we did observe a negative relationship between sediment pH and the Biota-Sediment Accumulation Factor (BSAF) of most PTEs for Oregon pill bugs (Gnorimosphaeroma oregonensis). G. oregonensis, observed at all sites, feeds on the fibers associated with the papermill discharge. Thus, G. oregonensis is a useful biomonitors for quantifying the impact of the decommissioned papermill, and are candidate biomonitors for assessing the impact of similar industrial development projects on intertidal ecosystems.

Relationships between concentrations of Potentially Toxic Elements (PTEs) in estuarine sediments and their impact benthic invertebrate communities are poorly understood. We sampled and analysed PTEs in sediments and benthic invertebrates from five sites surrounding the Skeena Estuary, including sites adjacent to an abandoned cannery and a decommissioned papermill. There was no indication that sediments of the salmon cannery are polluted, but acidic sediments adjacent to the papermill contained elevated concentrations of Cd, Cr, Hg and Pb. Benthic invertebrate community assemblages confirm that sediments have recovered from prior disturbances associated with discharge of papermill sludge. Oregon pill bugs (Gnorimosphaeroma oregonensis), observed at all five sites, feed on the fibers associated with the papermill discharge. Thus, G. oregonensis are useful biomonitors for quantifying the impact of the decommissioned papermill, and similar industrial development projects, on intertidal ecosystems along the north coast of British Columbia, Canada.

“…Metal pollutants, such as nickel (Ni), iron (Fe), manganese (Mn), zinc (Zn), copper (Cu), chromium (Cr), arsenic (As), mercury (Hg), lead (Pb), and cadmium (Cd), has become a serious global concern (Carvalho et al 2020;Singh et al 2020). Their contamination of many elements of the environment and ecosystem disrupts the natural biogeochemical cycle (Borah et al 2018; Kumar et al 2019;Guarda et al 2020). They are considered the most dangerous because of their non-biodegradability, ecological risks, toxicity, biogeochemical recycling, extended biological half-lives, and persistence (Bhatia et al 2015;Sharma et al 2018; Kaur et al 2020), and some are poisonous even at extremely low doses.…”

Metal contaminants such as Cadmium, Chromium, Nickel, and Lead are released and deposited in Reserved Forest soils as a result of heavily travelled roads. Their pollution interrupts the biogeochemical cycle in the natural environment, affecting plant productivity. However, this pollution's source, their ecological risks, and its effects on tree biomass productivity have yet to be examined. In order to examine this, an ecological study was conducted in two Assam Reserved Forests that are crossed by the National Highway (NH-15). Several ecological risk indices were used to assess potential ecological risks. Metal impacts on tree biomass stocks were predicted using regression analysis and Pearson's coefficient. The results showed that metal concentrations in soil samples collected near roads were much higher than those away from roads. However, the overall mean concentration was within the Indian guidelines. Indices of soil contaminations and pollutions ranged from mildly contaminated to highly contaminated and from low polluted to highly polluted soils. The Cd (88.97%), and Pb (52.61%) were revealed to be highly the main contaminating and sources of pollution and ecological danger in the surface soils. The strongest Pearson correlation coefficients between Cd-Cr (94%), Cd-Ni (74%), Cd-Pb (97%), Cr-Ni (88%), Cr-Pb (90%), and Ni-Pb (76%) suggest that metals are very comparable. While the strong negative relationships between tree biomass stock and metals, implying that metals are vital factors affecting tree biomass productivity. Thus, conservationists, ecologists, and policymakers must devise effective mitigation strategies for vehicular emission and car discharge caused by traffic passing through reserved forests.
