The inhibitory activity of aqueous extracts of field-grown sorghum (Sorghum bicolor cv. Bird-a-boo) herbage and roots was quantitatively indexed by three aspects of cumulative cress (Lepidium sativum cv. Curlycress) seed germination: the germination onset; weighted mean rate; and final germination percentage. Extract potency was greatest for herbage collected four weeks after planting but decli...

Soil pollution by some heavy metals including: Cr, Mn, Fe, Ni, Cu, Zn, As, Mo, Cd and Pb from northern industrial area of Erbil City was assessed. The contamination indices geoaccumulation (Igeo), factor (CF), enrichment (EF), degree (Cdeg), load index (PLI) element (ECI) were applied to assess soil in North Industrial at three sites (for both surface sub-surface soils). Maximum Fe value 34243....

Our study was a biological evaluation of soil contamination near a non-operating pesticide tomb. The soil contaminated with pesticides had a negative effect on the growth of crustaceans such as Heterocypris incogruens (Ostracodtoxkit test) and the development of plants such as Lepidium sativum, Sinapis alba, and Sorghum saccharatum (Phytotoxkit test). This adverse effect persisted up to 5 years...

rhelogical properties of mucilage extracted from garden cress (lepidium sativum l.) seeds as influenced by gum concentration (0.4, 0.6, 0.8 and 1.0 % w/w), temperature (5, 25 and 40 ?c), as well as ph (2.5, 4, 7 and 10) were investigated. non-newtonian shear thinning flow behavour was observed with the power law model well describing the rheological behavior of the solutions. increasing the sol...

Helichrysum stoechas (L.) Moench cell suspensions were analyzed by LC-ESI-QTOF, which highlighted the predominance of 3,5-O-dicaffeoylquinic acid (3,5-diCQA). Elicitation H. cells with methyl jasmonate (200 mM) led to a massive rise in 3,5-diCQA, up 5-fold-increase compared control, reaching concentration 10.2 mg. g-1dry weight after 14 days culture. Previous data showed that diCQA isomers are ...

Swimming pools are examples of water-intensive facilities, where solutions for reducing economic and environmental costs searched with increased frequency. One the supporting savings is recovery water from wastewater, including backwash obtained while rinsing filter bed. The study objective was qualitative quantitative assessment post-coagulation sludges, main pollutant found in washings. Durin...

High-affinity hydrogen (H2 )-oxidizing bacteria possessing group 5 [NiFe]-hydrogenase genes are important contributors to atmospheric H2 uptake in soil environments. Although previous studies reported the occurrence of a significant H2 uptake activity in vegetation, there has been no report on the identification and diversity of the responsible microorganisms. Here, we show the existence of pla...
