Response of peroxidase and catalase to acid rain stress during seed germination of rice, wheat, and rape

WANG Lihong, HUANG Xiaohua, ZHOU Qing

Frontiers of Environmental Science & Engineering 2008, Volume 2, Issue 3, Pages 364-369 doi: 10.1007/s11783-008-0053-5

Abstract: Seed germination of plants with various acid-resistance display different responses to acid rain.To understand the reason why such differences occur, the effects of simulated acid rain (pH 2.5–5.0)Results indicated that the maximum change in activities of CAT and POD by acid rain treatment with differentacidity and time in relation to the referent treatment without acid rain, was in the order: rice (28.8%The pH level for which the treatment with acid rain did not cause significant difference ( < 0.05) was

Particulate matter and metals partitioning in highway rainfall-runoff

Gaoxiang YING, John J. SANSALONE,

Frontiers of Environmental Science & Engineering 2010, Volume 4, Issue 1, Pages 35-46 doi: 10.1007/s11783-010-0009-4

Abstract: This study investigated the particulate matter (PM) and metals in highway dry deposition and rainfall-runoff as a function of hydrologic transport and settling on an event basis. Events were differentiated as mass-limited (ML) and flow-limited (FL). Results indicate that unique and separate suspended sediment concentration (SSC) relationships with turbidity occurred for ML and FL events. Sixty minutes of quiescent settling produced a single SSC-turbidity relationship for all events. ML events transport higher proportions of settleable and sediment PM while FL events transported relatively higher suspended PM. For batch clarification with one hour of settling, ML events had generally higher treatment efficiencies compared to FL events for the same settling conditions. Highway dry deposition PM was hetero-disperse and coarse ( = 304 µm). Results indicate that the acidic rainfall is not a significant contributor to metals in runoff but is capable of leaching metals from dry deposition PM into runoff. Partitioning in retained runoff resulted in a particulate-bound €predominance €for €most €metals €except Ca and Mg. While the finer fraction of dry deposition PM (<75µm) generates the highest metal concentrations, the highest metal mass is associated with the coarser fraction (>75µm).
