A 3D ecotoxi-topological profile: Using concentration-time-response surfaces to show peroxidase activity in Zea mays (L.) exposed to aluminium or arsenic in hydroponic conditions

This study sought to use concentration-time-response surfaces show the effects of exposure toxic (semi-)metals on peroxidase activity in higher plants as a function exposure-concentration and exposure-time. Maize (Zea mays L.) seedlings (i.e., leaves roots) were exposed arsenic (as As3+) or aluminium Al3+) under hydroponic conditions, their biomass enzyme responses assessed at different concentration-time-exposures. The 3D ecotoxi-profile generated with these data showed two distinct regions: first region is formed by exposures points for time-concentration pairings) that not statistically from results control zero toxicant concentration all exposure-times), whereas second pairings those obtained pairings. Overall, increased over shorter exposure-time when there was an increase toxicant, which can be seen 3-D toxicity profile. We propose quantitative relationship ratios endpoints (e.g., activity) enzymatic could helpful field environmental-policy management.
