In a three-year study, the response of four cultivars of chickpea, Bulgarit, WIR-32, Jordan and ICC 11293 to irrigation with TW （treated wastewater） and FW （freshwater）, using surface and subsurface drip irrigation was investigated. Wastewater generated from Al-Quds university campus included black, grey and storm water was treated by small scale pilot plant. The wastewater pilot plant consists of tailored made secondary biological activated sludge process with daily capacity of 50 m3. The influent and effluent chemical and biological quality parameters were routinely monitored and analyzed. The data reveal that the average values for BOD, COD and EC for the effluent are 50 ppm, 136 ppm and 1.4 mS/cm over 2 years period. The results of chickpea growth parameters and the chemical and biological analysis of the seeds and leaves indicate that the cultivars Bulgarit and ICC 11293 can be irrigated with TW without any loss in yield and quality. Factor analysis reasonably favored Bulgarit Cultivar irrigated with treated effluent over other cultivars. WIR-32 and Jordan cultivars showed significant reduction in their growth parameters when irrigated with TW as compared with FW. Surface and subsurface drip irrigation gave similar results in most cases. Soil analysis in this study showed no significant difference between irrigation with TW and FW.

Organic vapors from biomass burning are a major source of secondary organic aerosols(SOAs). Previous smog chamber studies found that the SOA contributors in biomass-burning emissions are mainly volatile organic compounds(VOCs). While intermediate volatility organic compounds(IVOCs) are efficient SOA precursors and contribute a considerable fraction of biomass-burning emissions, their contribution to SOA formation has not been directly observed. Here, by deploying a newly-developed oxidation flow reactor to study SOA formation from wood burning, we find that IVOCs can contribute ～70% of the formed SOA, i.e.>2 times more than VOCs. This previously missing SOA fraction is interpreted to be due to the high wall losses of semi-volatile oxidation products of IVOCs in smog chambers. The finding in this study reveals that SOA production from biomass burning is much higher than previously thought, and highlights the urgent need for more research on the IVOCs from biomass burning and potentially other emission sources.
