Di.solved Cu, Ph, Zn and Cd i. the Hai.ou Bay waters were measured to be res.ecti.ely i. the range concentrati.ns of 0.47-1.16 μg/dm^3, 0. 94-- 2. 36μg/dm^3, 1.28-4.83 μg/dm^3 and 0. 005-0.072μg/dm^3; wi.h res.ecti.ely average values of 0.78μg/dm^3, 1.36μg/dm^3, 3.14 g/dm^3 and 0. 03 μg/dm^3. Di.solved Cu and Zn concentrati.ns are relati.ely hi.h at the stati.ns near the Longkun Road Outfall for domesti. sewage, the Xi.yi.g Outfall for i.dustry waste water and the Hai.i.n i.land Estuary, but di.solved Pb and Cd concentrati.ns are low i. these stati.ns. The values i. Other stati.ns are comparati.ely homogenous. Verti.al di.solved Cu, Pb and Zn concentrati.ns at the bottom layer are hi.her than at the surface layer, but di.solved Cd concentrati.n appears to be on the opposi.e. The measurement res.lts of Cu, Pb, Zn and Cd i. suspended parti.le show that parti.ulate matters i. the Hai.ou Bay seawater play a role i. puri.yi.g heavy metals. The study on strong complexed form and non-li.ble form of di.solved copper show that the rati. of strong complexed form and di.solved form i. about 85%, and non-li.ble form i. very low wi.h a value lower than 5 nmol/dm^3. Therefore, copper i. the Hai.ou Bay seawater cannot cause i.fluence on mar.ne organi.ms.

Sesame i. an i.portant oi.seed crop i. Afri.a and Asi., owi.g to i.s hi.h nutri.i.nal quali.y seed and mar.et value. Vari.ti.n i. sesame seed components i.cludi.g oi., olei. aci.,li.olei. aci., and protei. was i.vesti.ated by near-i.frared reflectance spectrometry i. 139 samples collected from di.ferent countri.s. Oi. and protei. contents were between 40.8%and 60.3%(mean 53.0%) and 15.5% to 25.5%(mean 20.4%), res.ecti.ely. Li.olei. aci.,rangi.g from 31.8% to 52.4%(mean 46%) was more abundant than olei. aci.(31.8%–50.6%,mean 38.1%). Li.ht-seeded samples di.played hi.her nutri.i.nal quali.y, as they were ri.her i. oi., protei., and li.olei. aci. than dark seeds. Samples from Afri.a had hi.her oi. and li.olei. aci. contents, whi.e Asi.n samples had hi.her olei. content. The analysi. revealed West Afri.an sesame culti.ars contai.i.g especi.lly hi.h levels of seed components, whi.h may command hi.h mar.et values. Two clusters of sesame samples grouped by seed composi.i.n were obtai.ed, i.cludi.g one cluster wi.h hi.h oi. and olei. aci. content and the other wi.h hi.h protei. and li.olei. aci. content. Thi. study revealed that sesame samples from Afri.a and Asi. harbor hi.h vari.ti.n for major seed components and also provi.ed background i.formati.n for breedi.g hi.h-nutri.i.n vari.ti.s accordi.g to the demands of sesame seed mar.ets.
