The molecules produced by living organisms, natural products, are employed in our lives as flavors, fragrances, pharmaceuticals, nontraditional medicines, dyes, and pesticides, among other uses. The products of chemistry are employed in our food as preservatives, artificial sweeteners, thickeners, dyes, taste enhancers, flavors, and textnring agents. Chemistry creates such key materials as plastics, ceramics, fabrics, alloys, semiconductors, liquid crystals, optical media, and biomaterials. Chemistry also does many kinds of analysis and these include measurements of air quahty, water quality, food safety, and the search for substances that compromise the enviromnent or workplace safety. 

C below the melting point. The nature and the size of the exposed surface of the deposit on the leaf surface can be modified by spray adjuvants such as wetting agents, thickeners or particulating agents. The deposited pesticide may also interact with the target surface, with leaf exudates or with the polymeric wax-like surface of cutin. It may also physically penetrate the surface of the leaf.

Several systems may be used such as polymeric thickeners, fine particulate solids such as bentonite clays and oxides or combinations of the latter with polymers (1). The nature and level of the gelling agent required to prevent appreciable settling of particles and formation of hard "cakes" or clays depends on the density difference between disperse phase and medium, volume fraction of the disperse phase and interaction of the antisettling system with particles of the pesticide. 

The increase in gel strength with increase in bentonite concentration above the gel point is consistent with the increase in yield value and modulus. On the other hand, the limited creep measurements carried out on the present suspension showed a high residual viscosity Oq of the order of 9000 Nm s when the bentonite concentration was 45g dm. As recently pointed out by Buscall et al (27) the settling rate in concentrated suspensions depends on 0. With a model system of polystyrene latex (of radius 1.55 vim and density 1.05 g cm ) which was thickened with ethyl hydroxy ethyl cellulose, a zero shear viscosity of lONm was considered to be sufficient to reduce settling of the suspension with = 0.05. The present pesticide system thickened with bentonite gave values that are fairly high and therefore no settling was observed. 

The active ingredient (liquid or dry) is incorporated by a special process in small, permeable sph s of a polymer or plastic, 15 to 50 pm (1 pm = 10 m) in diameter. These spheres are then mixed with wetting agents, thickeners, and water to give the desired concentration of pesticide in a flowable form, usually 2 pounds per gallon. After the required dilution, the pesticide spray mixture can be applied with conventional sprayers. The pesticide is released gradually over a period of time.

Food additives can be considered conveniently from two standpoints, one from the standpoint of those used intentionally—e.g., preservatives, antioxidants, sequestrants, surfactants, stabilizers and thickeners, nutrients, colors, etc.—and the other from the standpoint of incidental additives such as those unavoidably becoming a part of food through their use in packaging material, animal feed supplements, or as pesticides for application to plant products. 

Pesticides and antimicrobials (biocides) are used in a number of plastics construction materials, mainly to provide resistance to the growth of microorganisms. One common example is their use in a number of PVC and PU grades. PU is commonly used for roofing membranes in construction [22], and several plasticisers, lubricants, thickening agents and fillers that are used with it can support microbial growth effectively.
