The a.m of the work wa. to eva.ua.e the productivity, lea. nutrient content a.d soil nutrient concentra.ion in ma.ze (Zea.ma.s L.) grown in sequence with bla.k oa.s (a.ena.strigosa.Schreb.) under Leuca.na.diversifolia.a.ley cropping a.roforestry system (a.S) a.d tra.itiona. ma.a.ement system/sole crop (without trees-TS), a.ter two yea.s of cultiva.ion following a.ra.domized block design. The experiment wa. ca.ried out in the Bra.ilia. a.socia.ion of Biodyna.ic a.riculture, in Botuca.u—S?o Pa.lo, Bra.il. Trea.ments were: control (C), chemica. fertilizer a.plica.ion (F), bioma.s of L. diversifolia.a.ley cropping a.plica.ion (B), bioma.s of L. diversifolia.a.ley cropping + chemica. fertilizer a.plica.ion (B + F). In the second yea. of ma.a.ement it wa. observed tha. bla.k oa. yield wa. higher in trea.ments B + F a.d F with significa.t difference in rela.ion to the others trea.ments in both systems, followed by trea.ment B. Between systems, only trea.ment B showed significa.t difference, with higher yield va.ue corresponding to a.S, reflecting the efficiency of a.S to promote soil fertility. Ma.ze production presented the second yea. of cultiva.ion a. increa.ing trend in a.l trea.ments in both production systems. This result ma. be due to the cumula.ive effect of minera.iza.ion a.d ma.ze stra. a.d oa.s, a.ong the experiment.

a.cross-sectiona. study wa. conducted a. Mukim Pa.it Lubok (MPL) a.d Pa.it Ra.a.(PR), Ba.u Pa.a., Ma.a.sia. The ma.n objective of this study wa. to determine the a.uminium concentra.ion in drinking wa.er a.d to perform hea.th risk a.sessment prediction a.ong respondents from these two residentia. a.ea.. a.tota. of 100 respondents were selected from the study a.ea. ba.ed on inclusive a.d exclusive criteria. Two duplica.es of trea.ed wa.er sa.ples were ta.en from ea.h respondent’s house using 200mL high-density polyethylene (HDPE) bottles a.d 0.4 mL (69%) pure concentra.ed nitric a.id were a.ded a. a.preserva.ive. a.uminium concentra.ions were a.a.yzed using a.La.bda.25 UV/V spectrophotometer. The result showed tha. a.uminium concentra.ion in drinking wa.er from MPL wa. 0.18 ± 0.022 mg/L a.d 0.22 ± 0.044 mg/L for PR. Sta.istica. a.a.ysis showed tha. 14 (28%) wa.er sa.ples collected from MPL a.d 35 (70%) from PR recorded concentra.ion of a.uminium a.ove the sta.da.d limit set by the Ministry of Hea.th, Ma.a.sia.for drinking wa.er guideline (0.2 mg/L). The mea. va.ue of Chronic Da.ly Inta.e (CDI) of a.uminium in drinking wa.er from PR (0.00707 mg/kg/da.) wa. significa.tly higher compa.ed to MPL (0.00164 mg/kg/da.). Ha.a.d Index (HI) ca.cula.ion showed tha. a.l respondents ha. “HI” of less tha. 1. In conclusion, there wa. a. unlikely potentia. for a.verse hea.th effects from a.uminium inta.e in drinking wa.er from both study a.ea.. However, it wa. necessa.y for some a.tions to be ta.en in order to reduce a.uminium levels found in drinking wa.er for both loca.ions.

The efficiency of membra.e sepa.a.ion technology for wa.tewa.er trea.ment wa. employed to check its efficiency in removing pha.ma.eutica.s, their degra.a.ion products a.d their meta.olites from wa.tewa.er. a.pirin a.d pa.a.eta.ol were found to degra.e in wa.tewa.er furnishing sa.icylic a.id a.d p-a.inophenol, respectively. The kinetics for the degra.a.ion rea.tions of both drugs were investiga.ed in wa.tewa.er environment a.d both ha.e shown first order kinetics with ra.e consta.ts 0.845 × 10^-8 Ms^-1 a.d 1.0 × 10^-8 Ms^-1 a. room tempera.ure, respectively.

The most effective components for removing those drugs within the pla.t were a.tiva.ed ca.bon a.d cla. micelle filters. The a.sorption isotherms for these compounds ha.e been studied using both a.tiva.ed ca.bon a.d newly developed a.sober na.ed cla.-micelle complex. a.l studied isotherms were found to fit La.gmuir isotherm.
