ABSTRACT
This research aims to find the impact of the nationwide partial and complete lockdowns on the environmental quality of Kuwait. This objective was accomplished by collecting roadside deposited sediments (n=54) at three periods during the first wave of the SARS-CoV-2 epidemic (complete-lockdown, partial-lockdown, and re-opening) from different locations in Kuwait and then analyzing them via ICP-AES for the presence of heavy metals and later applying various pollution indices. Extensive analysis of 162 subsamples showed that virtually all the minimum values were associated with the complete lockdown period (9 out of 10 elements). Pearson's correlation coefficients indicate that all elements are positively correlated except for Cu-Cd, Cu-Cr, and Co-V, suggesting that the sediments share a common source. Except for cadmium and copper, almost all sediments showed low ecological risk potential (Eri < 40). The lowest risk index was during the complete lockdown (RI=162.2). The full lockdown period had marginally lower geo-accumulation indices and classes than the partial lockdown and re-opening periods. The improvement in sediment quality between the different periods was minimal due to low levels of commitment in the governmental curfew leave permissions, the continuity of Kuwait municipality manual and mechanical road cleanup processes during lockdowns, and the associated energy consumption with emissions resulting from extended indoor stay. © 2023, ALÖKI Kft., Budapest, Hungary.
