Gonzalez and Esquivel (1979) as part of their study on lead in soil in Mexico City, analyzed also the vegetation growing at the sides of the avenues selected for the study. Their results are shown in Table 18 the large difference between the washed and the unwashed samples is evident. They found that lead concentrations were higher in samples from the north-northwest of the city, as had happened with the soils. 

These two studies were carried out before the reduction on lead in gasoline sold in the MZMC was supposed to come into effect. There are no further data.

Steroid alkaloids have been isolated from four famihes of terrestrial plant sources (Soianaceae l iliaceae pOijnaceae and Buxaceae) two animal sources (Saiamandra and Phjllobates) and several marine sources. Steroid alkaloids can be classified based on stmcture and fall into a variety of categories. The spirosolanes contain a cholestane skeleton with a C20 spiroaminoketal moiety, as exemplified by the most abundant members of this class, veramine... 

An average of about 7 ppm of bromine is found ia terrestrial plants, and edible foods contain up to 20 ppm. Among animals the highest bromide contents are found ia sea life, such as fish, sponges, and cmstaceans (44). Animal tissues contain 1—9 ppm of bromide and blood 5—15 ppm. The World Health Organization has set a maximum acceptable bromide iatake for humans at 1 mg/kg of body weight per day. In adult males the bromine content ia semm has been found to be 3.2—5.6 p.g/mL, ia urine 0.3—7.0 p.g/mL, and ia hair 1.1—49.0 p.g/mL. Bromine may be an essential trace element as are the other hahdes (45).

The held of marine natural products chemistry, which encompasses the study of the chemical structures and biological activities of secondary metabolites produced by marine plants, animals, and microorganisms, began in earnest in the early 1960s.

Lifeforms include the operator, the plant neighbor, the general public, the ultimate consumer of the product. They also include the aquatic and terrestrial plant, fish and animal life. 

The ECOTOXicology database is a source for locating single chemical toxicity data for aquatic life, terrestrial plants and wildlife. ECOTOX integrates three toxicology effects databases AQUIRE (aquatic life), PHYTOTOX (terrestrial plants), and TERRETOX (terrestrial wildlife). These databases were created by the U.S. EPA, Office of Research and Development (ORD), and the National Health and Environmental Effects Research Laborator) (NHEERL), Mid-Continent Ecology Division... 

Mosses and liverworts (Bryophyta) are more complex than algae. Some of the larger species have structures that superficially appear similar to roots, stems and leaves, but they lack the internal conducting systems present in the vascular plants (Tracheophyta). Internal transport systems (vascular systems) make possible the large sizes of terrestrial plants where the soil is the source of some requisites (water, mineral nutrients) and the air is the source of others (CO2, sunlight). The different groups of vascular plants are characterized primarily by their methods of reproduction. Vascular plants are the source of all wood.

In contrast to the TPA-type tumor promoters, palytoxin, thapsigargin, and okadaic acid are classified as non-TPA type tumor promoters, which do not bind to phorbol ester receptors, or activate protein kinase C in vitro (Table II) (6,25-27). In this chapter, thapsigargin is not discussed, because it is derived from terrestrial plants.
