4.2 Most important symptoms/effects, acute and delayed

Tremors, convulsions, shortness of breath, inhibition of respiratory system. (USCG, 1999)

4.3 Indication of immediate medical attention and special treatment needed, if necessary

Immediate first aid: Ensure that adequate decontamination has been carried out. If patient is not breathing, start artificial respiration, preferably with a demand-valve resuscitator, bag-valve-mask device, or pocket mask, as trained. Perform CPR as necessary. Immediately flush contaminated eyes with gently flowing water. Do not induce vomiting. If vomiting occurs, lean patient forward or place on left side (head-down position, if possible) to maintain an open airway and prevent aspiration. Keep patient quiet and maintain normal body temperature. Obtain medical attention. /Phenols and related compounds/

6.Accidental release measures

6.1 Personal precautions, protective equipment and emergency procedures

Use personal protective equipment. Avoid dust formation. Avoid breathing vapours, mist or gas. Ensure adequate ventilation. Evacuate personnel to safe areas. Avoid breathing dust. For personal protection see section 8.

6.2 Environmental precautions

Personal protection: chemical protection suit including self-contained breathing apparatus. Do NOT let this chemical enter the environment. Sweep spilled substance into covered containers. If appropriate, moisten first to prevent dusting. Carefully collect remainder. Then store and dispose of according to local regulations.

6.3 Methods and materials for containment and cleaning up

Activated carbon is a good method for removing chlorophenols from water. Competitive adsorption occurs between chlorophenols & humic substances present in nearly all municipal water supplies. This competition decr the capacity of carbon for chlorophenols. /Chlorophenols/

7.Handling and storage

7.1 Precautions for safe handling

Avoid contact with skin and eyes. Avoid formation of dust and aerosols. Avoid exposure - obtain special instructions before use.Provide appropriate exhaust ventilation at places where dust is formed. For precautions see section 2.2.

7.2 Conditions for safe storage, including any incompatibilities

Fireproof. Store in an area without drain or sewer access. Provision to contain effluent from fire extinguishing. Separated from strong oxidants and food and feedstuffs. Ventilation along the floor.SRP: Local exhaust ventilation should be applied wherever there is an incidence of point source emissions or dispersion of regulated contaminants in the work area. Ventilation control of the contaminant as close to its point of generation is both the most economical and safest method to minimize personnel exposure to airborne contaminants.

• Toxicity to daphnia and other aquatic invertebrates: EC50; Species: Daphnia magna (Water flea); Conditions: freshwater, renewal; Concentration: 3900 ug/L for 24 hr; Effect: behavior, equilibrium

• Toxicity to microorganisms: no data available

12.2 Persistence and degradability

AEROBIC: Using a static-culture flask-screening procedure with a settled wastewater inoculum, 2,4-dichlorophenol was found to be degradable with rapid microbial adaptation as 99-100% of initial concentration were degraded within 7 days(1). Using a Warburg respirometer and phenol-adapted bacteria (bacteria isolated from garden soil, river mud, compost and waste lagoon sediment), 95% of initial 2,4-dichlorophenol (200 ppm) was degraded within 7-10 days(2). Based on COD determination, 98% of initial 2,4-dichlorophenol was degraded in a BOD system with an activated sludge inoculum during a 20-day inoculation period(3). When activated sludge was exposed to 2,4-dichlorophenol at levels of 100 mg/L of sludge, 75% of the chemical disappeared in two days, and essentially 100% was gone in five days(4). However, 2,4-dichlorophenol, present at 100 mg/L, reached 0% of its theoretical BOD in 4 weeks using an activated sludge inoculum in the Japanese MITI test(5).

12.3 Bioaccumulative potential

A BCF range of 7.1 to 69 was calculated in fish for 2,4-dichlorophenol(SRC), using carp (Cyprinus carpio) which were exposed to 30 ppb test compound over an 8-week period(1). The BCF of 2,4-dichlorophenol in goldfish ranged from 34 to 100(3,4); the BCF in an unspecified fish specie was 100(3) and in trout was 10(4). According to a classification scheme(2), these BCF values suggest the potential for bioconcentration in aquatic organisms is low to moderate(SRC). The BCF of 2,4-dichlorophenol in algae ranged from 257 to 263(3,4).

12.4 Mobility in soil

The Koc of 2,4-dichlorophenol ranged from approximately 200 to 5,000 in soil adsorption studies using five mineral soils(1); the most important factors controlling the degree of adsorption were pH and percentage of iron oxide in the soil(1). In batch soil adsorption experiments conducted at pH 10, 2,4-dichlorophenol exhibited a soil equilibrium partition coefficient (Kp) of 0.0+/-0.5 indicating that adsorption was not occurring(2); 2,4-dichlorophenol has a pKa of 7.8 at 20°C which indicates that it will exist predominantly in the ionized form at pH 10(2); ionized phenols will generally not sorb to neutral or negatively charged soil organic matter as well as the non-dissociated form(2). The adsorption of the dichlorophenol isomers (including 2,4-dichlorophenol) onto Wyoming bentonite clay was found to be pH dependent with maximum adsorption occurring when ionization of the isomers was less than 50% based on pKa values(3). A 2,4-dichlorophenol Koc of 126 was measured in a clay loam soil from Michigan State University(4).
