Application
Herbicides are chemicals that inhibit, retard or kill plant growth.
Herbicides affect metabolic growth within the plant and should be
handled appropriately. Overexposure to herbicides can lead to an
array of health affects that include irritation to eyes, skin,
mucous membranes, and respiratory tract. Large doses of certain
herbicides can lead to vomiting, diarrhea, headache, confusion,
bizarre or aggressive behavior, anorexia, weight loss, severe
metabolic acidosis, ulcers of the mouth and pharynx, and toxic
injury to liver, kidneys, and central nervous system. Children are
especially susceptible to overexposure, with health affects ranging
from respiratory distress and cerebral palsy, to impaired
development.
Direct dermal exposure, inhalation, and ingestion
are the most common exposure routes . Water-soluble herbicides are
not retained in body tissues for long periods, as were the old
lipophilic organochlorine insecticides, such as DDT. Most are
excreted, mainly in the urine, within one to four days.
These herbicides can be found in buildings if the
product is applied indoors, improperly stored indoors, or enters the
structure through infiltration or by being tracked into the building
on clothing or in dust.
Required Equipment for Water and Soil Sampling
- Sterile Glass Jar for Soil
- Sterile Amber Glass Bottle for Water
Sampling Methods for Herbicides in Water or
Soil
- Using gloves, collect the water or soil sample
in the sterile container. Depending on sampling and project
specifications, samples can be collected from the immediate
source or composites of different time intervals or different
sample locations.
- Replace cap and label sample container
appropriately. If shipping sample to laboratory, ensure adequate
packing material surrounds container to prevent breakage in
transit.
- Samples should be shipped cold and be received
at laboratory as soon as possible.
Quality Control
Multiple samples should be collected for comparison studies to
include at a minimum: a suspect sample and a sample from an outside
source that lacks potential contamination.

Microbial Fact #1:
Staphylococcus is a Gram-positive bacterium that has a
thick-walled, spherical morphology and carotenoid pigment that
affords protection from ultraviolet light and desiccation. Most
Staphylococcal species are common inhabitants of the human skin and
mucous membranes. For example, large populations of
Staphylococcus capitis are commonly found in large populations
on the human head, especially the scalp and forehead where sebaceous
glands are numerous and well developed. Staphylococcus aureus
prefers the anterior nostrils as a habitat.
Skin infections caused by Staphylococcus aureus
are the most common human staphylococcal infections. These include
cellulitis, pustules, boils, carbuncles, impetigo and postoperative
wound infections. A common community acquired disorder is food
poisoning caused by thermostable enterotoxins released into foods
during growth of S. aureus. Other common staphylococcal pathogens
are S. epidermidis, S. saprophyticus, S. intermedius and
S. hyicus.
Fungal Fact #1:
A variety of different fungi are currently approved by the EPA for
use as fungicides and insecticides. These pesticides provide
natural, safe ways of preventing the growth of unwanted insects and
of fungi that cause plant disease. A specific example is
Gliocladium. Gliocladium catenulatum strain J1446 has
been commercially sold as Primastop and is approved only for indoor
use. Gliocladium virens GL-21 has been sold as SoilGard and
can be used both indoors and outdoors. Both preparations are used to
prevent rot and other root diseases.
